Which functional group is present in the compound ?

medium MCQ 2 marks Class 10 · Science · Carbon and its Compounds
  1. Carbonyl group
  2. Hydroxyl group
  3. Amino group
  4. Carboxyl group
Answer
Hydroxyl group

The correct answer is Hydroxyl group — Answer: Hydroxyl group.

Step-by-step solution

  1. Identify the group attached to the carbon chain: an –OH group is present at the terminal carbon.
  2. Recall that an –OH group defines an alcohol, i.e., a hydroxyl functional group.
  3. Check the other options: carbonyl, amino and carboxyl groups are not present in this structure.
  4. Thus the correct functional group is the hydroxyl group.
  5. Answer: Hydroxyl group.
Common mistake: Confusing the –OH group with a carboxyl group

Concept tested: Functional group identification
